GREENGUARD® Gold

Certifies that Knauf Performance+® products meet the world's most rigorous chemical emissions standards - protecting the health of sensitive populations including children and the elderly in schools, healthcare facilities, and commercial environments.

Asthma & Allergy Friendly®

The Asthma and Allergy Foundation of America (AAFA) joined with Allergy Standards Limited (ASL) to create the Asthma & Allergy Friendly® Certification Program. We test household products against strict standards. If products pass our tests, they earn the Asthma & Allergy Friendly® Certification Mark. When you see this mark, you know the product is proven to be better suited for people with asthma and allergies.

Verified Healthier Air™

Independent verification that the system performs as installed. Confirms the air quality benefits designed into Knauf Performance+® products hold up under real-world operating conditions - closing the gap between design intent and built performance.

Validated Formaldehyde Free

Formaldehyde is a common indoor air pollutant that can have adverse health effects. By obtaining the UL 2884 validation, Knauf confirms zero added formaldehyde in our product's composition.
